1940 decision event [so Japan was not at war with the Western Allies yet], giving the UK some Eastern/Pacific minors, but risking having Burma become unstable. Went with yes, just to see what would happen--couldn't be THAT bad, could it?
Two partisans immediately spawned in two inland cities. OK, the Indians had nothing better to do, so they + 2 Malaysian corps went in to take it all back.
The weird thing is that, even tho I could attack and damage them, I couldn't enter any enemy controlled hexes. At first I just assumed it was the jungle penalties holding me back, so bought a tank, but it couldn't enter them either [one hex away] despite high supply and full movement.
I'm guessing they were Japanese-controlled, who were still not at war with the Commonwealth, but if so why could I attack them? Note India couldn't enter any Chinese hexes either.
